Detailed explanation-1: -The hematocrit measures the volume of red blood cells compared to the total blood volume (red blood cells and plasma). The normal hematocrit for men is 40 to 54%; for women it is 36 to 48%. This value can be determined directly by microhematocrit centrifugation or calculated indirectly.
Detailed explanation-2: -Hematocrit is the percentage of red cells in your blood. Normal levels of hematocrit for men range from 41% to 50%. Normal level for women is 36% to 48%.
Detailed explanation-3: -Red blood cells make up about 45% of the blood volume. White blood cells make up about one percent and platelets less than one percent. Plasma makes up the rest of the blood. Mature red blood cells do not have nuclei or other organelles.
Detailed explanation-4: -Hematocrit is a measure of the portion of blood occupied by cells (red blood cells, white blood cells and platelets). A hematocrit of 0.40 L/L (litre of cells per litre of blood) indicates that 40% of the blood volume is composed of cells, with plasma making up the other 60%.
